800CW acid(CAT: I040435) is a near-infrared (NIR) fluorescent dye featuring a reactive carboxylic acid group, ideal for covalent labeling of proteins, peptides, or other biomolecules. With strong absorption and emission in the NIR region, 800CW acid offers high sensitivity and low background interference, making it exceptionally well-suited for in vivo imaging applications. Its long-wavelength emission allows deep tissue penetration and minimal autofluorescence, enabling precise visualization of biological targets in live animal models. 800CW acid is widely used in optical imaging, biodistribution studies, and the development of targeted diagnostic probes for preclinical research and biomedical applications.
